Pasteurella spp

From Cow
Classic pasteurellosis in lung of a steer.

Pasteurella spp are a genus of Gram-negative, facultatively anaerobic bacteria which are known to be pathogenic to cattle.

Pasteurella multocida, together with Mannheimia haemolytica and Histophilus somni is involved in the etiology of Bovine respiratory disease.

These bacteria are generally susceptible to chloramphenicol, penicillins, tetracycline, enrofloxacin and ceftiofur[1].

A number of vaccines against bacterial respiratory pathogens are commercially available[2].
